The rates of complicated hypertension, coronary heart disease, peripheral neuritis, diabetic renopathy, diabetic retinopathy, hyperlipoidemia, urethritis, diabetic acidosis, pneumonia, fatty liver, diabetic foot gangrene, cholecystitis, skin infection, brain vessel disease and vegetative nerve disease were 46.9%, 33.2%, 29.7%, 25.4%,22.0%,13.0%,7.5%,4.2%,4.0%,4.0%,3.5%,3.5%,3.3%,2.9%,and 2.0%, respectively. Conclusion The frequency of diabetic complications of patients with type 2 diabetes mellitus were much high, and the distrubution of diabetic complications was different in different ages, course of disease and syndromes.

Objective To observe the influence of combined spinal and epidural anesthesia( CSEA) of different po-sitions on the anesthesia effect, anesthesia operation and hemodynamic index during cesarean section of obese par-turients. Methods Eighty obese parturients[BMI≥30] undergoing cesarean section were randomly divided into two groups, that was group A and B, with 40 cases each. In group A, the parturients were required to undergo lat-eral decubitus position with 0.5% ropivacaine hydrochloride of 2. 4 ml. In group B, the parturients were required to undergo sitting position with the same ropivacaine hydrochloride as group A. The following data was recorded, which were the percentage of one-attempt's successful epidural needle placement, the anesthesia level,the anesthe-sia effect and the hemodynamic change. All the complications were also observed,such as the supine hypotension syndrome during operation,headache after spinal anesthesia and postoperative spinal nerve stimulation. ResultsThe difference of anesthetic effect between the two groups was insignificant in statistics while group B's rate of one-attempt successful puncture was higher than gruop A ( P <0.05 ) . The difference of hemodynamic index between them was significant in statistics ( P<0.05 ) with group B's rate of supine hypotension syndrome lower than group A. Conclusion Both body positions have the same anesthtic effect for obese parturients during cesarean section while the puncture operation of sitting positon is easier than lateral decubitus position and the hemodynamic change is also more stable.

Objective To investigate the effects of parecoxib pretreatment on the intrapulmonary shunt during one-lung ventilation in patients undergoing esophageal cancer resection.Methods Forty ASA Ⅰ or Ⅱ patients of both sexes,aged 25-64 yr,weighing 45-70 kg,with body height 156-178 cm,undergoing elective esophageal surgery,were randomly divided into 2 groups (n =20 each):normal saline group (group NS) and parecoxib group (group P).Parecoxib 40 mg (in normal saline 10 ml) was injected intravenously 30 min before anesthesia in group P,while the equal volume of normal saline was given instead of parecoxib in group NS.Anesthesia was induced with iv injection of propofol,fentanyl and rocuronium.Bronchial blocker was inserted after tracheal intubation and the correct position was confirmed by bronchoscopy.Anesthesia was maintained with iv infusion of propofol and remifentanil and intermittent iv boluses of atracurium.HR,MAP,SpO2 and mean airway pressure (Pmean)were determined at 5 min of two-lung ventilation,at 40 min of one-lung ventilation,and at 30 min after re-expansion of the collapsed lung (T0-2).Blood samples were taken simultaneously from jugular vein and radial artery for blood gas analysis.Intrapulmonary shunt (Qs/Qt) was calculated.Results There were no significant differences in hemodynamic parameters and Pmean between the two groups (P ＞ 0.05).PaO2 was significantly lower,while Qs/Qt was significantly higher at T1,2 than at T0 in groups NS and P (P ＜ 0.05).PaO2 was significantly higher,while Qs/Qt was significantly lower at T2 than at T1 in groups NS and P (P ＜ 0.05).Qs/Qt was significantly lower at T1,2 and PaO2 was significantly higher at T2 in group P than in group NS (P ＜ 0.05).Conclusion Parecoxib 40 mg injected intravenously at 30 min before anesthesia can reduce the intrapulmonary shunt during one lung ventilation in patients undergoing esophageal cancer resection.

Objective To explore the expression of Survivin and MHC in non-small cell lung cancer (NSCLC), and their interaction.Methods A total of 40 patients with histologically diagnosed NSCLC were enrolled in this study.Control samples were consisted of normal lung tissues from 15 patients.Expression of Survivin and MHC were detected by flow cytometry in 40 non-small cell lung cancer tissues and 15 normal lung tissues.Results The positive rates of Survivin protein expression in NSCLC tissues classified stages Ⅰ,Ⅱ and Ⅲ were 28.57% ,30.77% and 80.00% respectively.There was a correlation between Survivin protein expres-sion and stages of NSCLC.Survivin protein expression was detected in 19 of 29 patients with lymph node metas-tasis, and 3 of 11 patients with no metastasis.There was a statistically significant difference between the two groups (P<0.030).The loss expression rates of MHC-Ⅰ in NSCLC tissues of low grade,intermediate grade and high grade were 84.62% ,42.10% and 37.50% respectively.There was a correlation in expression be-tween MHC-Ⅰ and tumor grade.The positive rates of MHC-Ⅱ expression in NSCLC tissues was related to pa-thology type (P=0.005).The expression in squamous cancer and non-squamous non-adno cancer was lower than that of adenocarcinoma (P=0.002, P=0.04).There was no obvious correlation between the expression of Survivin and MHC-Ⅰ,MHC-Ⅱ in NSCLC.Conclution The expression of Survivin and MHC could be in-volved in the pathogenesis and development of NSCLC, and the combined detection will predict the prognosis of the patients with NSCLC.

Objective To investigate the patterns for the recurrent and metastatic gastric cancer after curative resection and to indicate the strategy of treatment. Methods 162 patients who had received radical resection and presented post-operation failure during recent 9 years were analyzed. The failure patterns were confirmed by type-B ultrasonic or CT / MRI imaging. 15 of 34 patients with abdominal dropsy were diagnosed by adenocarcinoma cells in the abdominal dropsy. All superficial lymphadens and abdominal wall metastasis were diagnosed via punctuation. 31 patients with gastric remnant and (or) anastomoses recurrence were diagnosed via biopsy. Results Of 162 patients, 63 presented the recurrence or metastasis in multiple sites,including abdominal lymph node (LN) metastases in 46.9 % (76/162), peritoneum metastases in 21.0 % (34/162),gastric remnant and (or) anastomoses recurrence in 19.1% (31/162), liver metastases in 19.1% (31/162), the incidence rates of other parts were all ＜10 %. Meanwhile, out of 76 patients with abdominal lymph node metastases, 48.7 % (37/76) patients with peri-gastric LNs metastases, 31.6 % (24/76) with peri-pancreatic LNs metastases, 19.7 % (15/76) with para-aortic LNs metastases. The incidence of LN metastases was 57.7 % (56/97) in cancer arising from gastric fundus/cardia and 60.4% (29/48) in gastric body and 64.7 % (11/17) in pylorus antrum. Conclusion The regional failure sites for gastric cancer patients with radical resection were dominantly found in the gastric stump/stoma, the peritoneum and pelvic cavity implantation and abdominal cavity LN metastases, especially in the peri-gastric, peri-pancreatic and/or para-aortic LN metastases. The distant place failure sites were mainly in the liver, lung, brain, spondylus, cervical part LN and mediastinal LN metastases. Therefore, we should take chemotherapy, abdominal cavity chemotherapy and regional radiotherapy to prevent the regional district recurrences and distant metastasis after the gastric cancer patients with radical resection. Radiotherapy fields should focus on the gastric stump/stoma and the peri-gastric, peri-pancreatic and para-aortic LN regions.
